Wringer-rolls.



`plication to any `set 'rolls To all whom t may concern.' l Y Be it known that I, FREDERICK G. SARGLNTQv a. citizen of the United States, residing at W'estford, in the countyfof Middlesex and State of Massachusetts, have invented new and useful lVringer-Rolls, of which the following is a. specification. i

This'invention relates to the wringer rolls of washing machines but is cpableofjap- -lhe principal objects of the invention are tc provide a construction by which certain vkinds of stock, such as pulled cattle hair and the like, can-be passed through the rolls in a successful manner. Stock ofthis kind is passed through Ordinary rolls with diliculty as it is of an irregular character und contains bunches and hard compact messes of hair.

This invention is designed to do away with this didiculty and at the seme time provide s. set of rolls suitable for general use, but particularly applicable to Wool and hair washing machines can be left between the 'two rolls.

inference is to -be had to the accompanying drawing, in which- I IIigure 1 is s front elevation of a pair of wringer rolls and the supportstherefor, showing one of the rollspartly in longitudinil section, and Fig. is; a. similar view of a mcdiiication. l

This invention involves the usevof a. pair of rolls. one of 4which consists of a corel or mandrel of hard material covereclwith soft rubber er lapping' and the other of which has n. herd surface. At- ,the ends of one roll ineens are provided for bearing directly on the other roll with some pressure, 'while the the adjacent surfaces of initerznediate port-ion is spaced from it or pressure. Either the bot-V be'srs with@ iight toin roil'cir the top roll can be made in this ser, er both! En Fig. 1 the invention is'shown as applied to e. wool and hair v weshing machine hering- :i bottom roll 10 of iron or steel which may be covered with e brass jacket. tithe end this roll is provided with a. pair uffcircinnierentie grooves 11 to receive the lifuid to .er ent its running on the bearings.

mandrel 18. At the ends of this mandrel are a. pair of hard rubber rings 14 and between these rings the mandrel. is covered with soft rubber or lapping l which is slightly smaller in diameter than the hard rubber rings. If lapping is used it is in the. form ovvorstedi slubbing wound on'v between the raised flanges 14. Of course any otherv soft material usually employed on rolls ofthis character can be substituted for the soft rubber. The ends 14 can be in the form of Vdisks or of rings covering the ends of man;

drel 13. The hard rubber rings 14 rest 'upon the roll and the'hair or Wool can be put through the rolls under all .ordinary conditions, because the hard rubber ends keep the soit rolling surface 15 slightly away fromthe surface of the roll 10 and thepres sure, when there is no stock between the rolls, is received at the ends of the rolls.

In Fig. 2 the invention is shown as applied to a plain rubber-covered top roll 2O and a hard bottom roll 21. The ends 22 of the bottom roll support the tonroll; The bottom roll has :i slight depression 23 to enable the Although I have illustrated and described only `two embodiments of ein aware of the fact that tions can be made therein I ing from the scope of the invention is ex; claim.
